HEART MATH:

This is a computerized program that has an element similar to Biofeedback. As you watch the screen on a computer and practice a particular method of rhythmic breathing, while being connected to the computer via a light clip attached to your earlobe, you can begin to bring greater synchronicity between your heart, brain and autonomic nervous system. Incorporating positive thoughts and feelings not only increases that synchronicity, but also teaches your body and mind how to work together more effectively, and to manage life stresses more easily.
